Gnumeric can open files which have been created in several formats by other spreadsheet programs or databases. The details of these formats are provided in Section 9.2 ― File Formats and the name of each file type in the table below skips to the appropriate section of Section 9.2 ― File Formats. The opening of text formatted files is described in Section 9.4 ― Importing Text Files. Gnumeric can also import text data or HTML and XHTML tables through the clipboard mechanism, as is explained in Section 5.7.4 ― Cut and Paste Between Gnumeric and Other Applications.
Most of these formats are provided by plugins, which are independent, configurable modules. If a format described below does not appear in the File Open dialog, this may be because the appropriate plugin has not been configured or started. This can be verified by examining the list of plugins which are currently running in the Plugin Manager dialog.
The Plugin Manager dialog lists the plugins which are currently in use and provides a way to start plugins which are currently disabled. The Plugin Manager can be started by selecting, in the Tools menu, the Plug-ins... menu item; see Section 8.4 ― Plugins for more information.
